(E)AC3, DTS, MPEG-H support in tinycompress and the kernel uapi?

Have there been discussions about adding support for (E)AC3, DTS, and MPEG-H? These days, 3D Audio is a use case where the Compress-Offload API is useful. It therefore would make sense to add support for these formats. I'm talking about direct support, not through IEC958 / IEC61937 payloading. I know that some HW vendors add their own custom changes to tinycompress to support these formats, so why not add these to upstream?

[dbaluta]

no discussions AFAIK. But patches are welcomed.

But since this would also require changes to the sound/compress_params.h kernel UAPI header, how should this start? Should a tinycompress PR be preceded by a discussion about extra formats in the linux-media mailing list?

[dbaluta]

Ideally you should first create a patch for alsa devel mailing list introducing new formats followed by a PR here where you update the UAPI header and add the implementation.

it doesn't really matter the order. what it matter is to send the patches and people will guide you.
